The collection ID for the 2023 Turkey Earthquake is Kahramanmaras-turkey-earthquake-23. We can get the footprints (geojson, tsv) of the event from the Maxar Open Data GitHub repo:
In [4]:
Copied!
collection = 'Kahramanmaras-turkey-earthquake-23'
url = leafmap.maxar_collection_url(collection, dtype='geojson')

url
Out[4]:
'https://raw.githubusercontent.com/giswqs/maxar-open-data/master/datasets/Kahramanmaras-turkey-earthquake-23.geojson'
Let's find out how many images are available for the event:

Create a split map to compare the pre-event and post-event images. Note the the ipyleaflet split map has some bugs (source), so we will use the folium plotting backend instead.
